How to retrieve files from a WD My Book World Edition II with two 2TB drives.

A little background:
I bought this WD NAS over ten years ago and it has ran fine up until about six weeks ago
when it died. Windows 7 just no longer sees the mapped out drives in My Computer. There
were no sounds coming from the spinning drives just nothing. So I decided it was a WD
enclosure problem and not a hard drive problem. So I pulled the hard drives from their
enclosure and connected one of them to a “USB to SATA Adapter”, then plugged it into my
computer. The computer made a sound of a USB device being plugged in, but nothing
showed up in My Computer window. My conclusion is that I would have to look elsewhere
for my answer if I wanted my data back.

So I started my research on the internet, and found there are a lot of people with the
same problem and no support or fix from WD to correct it. I found that some people had
success with Linux. I have an older DELL laptop laying around so I loaded Linux Mint 20
“Ulyana” – Cinnamon (64-bit) on to this older DELL. I can at least see the drive now in
the My Computer window but can’t get into it. When I try, I get the error message “Unable
to mount location”.

In the past six weeks I have read and tried countless internet posts, most of them have
been Terminal Window stuff without any success. I know there is a solution out there, I
just need someone’s help to find it.

If you are willing to take on this challenge, you will find that I’m highly motivated to
retrieve my data. I promise to check this forum every day and try your suggested key
strokes and post results.

Shown below are two looks at both drives “Disks” & “sudo fdisk -l”. I’m hoping that if
someone is willing to help me this will be useful to you.

Thank You in Advance
